Sean Johnson's 2015 is over. The Chicago Fire announced that the goalkeeper has a labral tear in his left shoulder and will not play again this season.
The good news for Johnson is that his injury will not require surgery. That should keep his time on the sidelines limited to a few months and he'll even be able to train on a limited basis, staying fit while his shoulder is rested.
Chicago aren't technically eliminated from playoff contention, thanks to a horrific Eastern Conference, but they're the worst team in MLS and don't have a realistic chance at making the postseason so the decision to rest him wasn't a tough one. It's more important that he be healthy than they get points at this point.
Johnson has served as one of the United States' rotating band of backup goalkeepers, something he'll be ruled out from for the remainder of the year, but that's not much of an issue. While it's nice to get him some experience in training with the national team, he's well down the pecking order. Brad Guzan and Tim Howard are the clear-cut top two right now, while Nick Rimando is still in the mix and Bill Hamid looks to be the best young goalkeeper in the pool right now. Johnson will probably be back in the national team come January camp, assuming his shoulder has healed by then.
